Lexar’s Professional 133x SDXC cards are now shipping in the jumbo sizes of 64GB and 128GB. These new SDXC cards carry retail prices of $199 and $329, respectively. (Although, the street prices are substantially less. See below.)

Panasonic introduced new SDXC cards in 64GB and 48GB capacities at CES 2010.

SDXC cards are a new standard from the SD Association that allows for capacities ranging from 64GB to 2TB. SDXC cards also have a speed advantage over the SDHC format. The SDXC format has a theoretical speed of 104MB/s to potentially 300MB/s in the future.

It is important to note that SDXC cards are not compatible with camera models that are not specifically designed with the SDXC format in mind.

The Panasonic 64GB SDXC card carries an initial retail price of $599.95, while the 48GB SDXC card has an initial retail price of $449.95.
